Hi,
I have problems when updating my tabbed panels :'(
After modifying the data on one panel I update several other panels, that are not
necessarily connected together.
Using only #update e.g. (browser paneNamed: #example) update.
The data is correctly updated, but not the presentations.
Based on the example #updateableBrowser I am showing the errors.
1) #when in the second list does not react.
* If you start with an empty collection, the list does not appear, then if you add an
element the list does not appear neither.
* if you start with some elements, the list is there, but after removing all the elements
the list does not disappear, and instead you have a SubscriptOutOfBounds error because of
a tab index (this is my same scenario: tabbed panels)
2) #shouldValidate: what is the logic of this?.
I tried to use it, but i got into problems on the selected item. I could only inspect the
selected item of the panel using #shouldValidate. In the second panel -> selected item
is nil or the value of the first panel.
